Amazon just unveiled a major overhaul of the Kindle app — here's what's new

The update includes a cleaner, more modern interface and a new page turn feature.

The Kindle app is available for iOS and Android smartphones and tablets, as well well as Macs and PCs.

The Kindle app just got a major makeover.

Amazon on Tuesday unveiled a total overhaul of the app, which lets you read ebooks and magazines on any device — including iPhones, iPads, Android phones, and even PCs.

The most notable change to the app is its new streamlined look. It has a cleaner, easier-to-use design and two different color themes — light and dark.

The app also features a cool new page turn feature, which makes it easier to look for something on another page without losing your place. Here's the feature in action:

Amazon also added its Goodreads social network into the iOS app, which lets users connect with people who share the same taste in books. Amazon bought Goodreads in 2013.

Some other new features include:

The option to easily share quotes or book recommendations with friends

Amazon's "x-ray" feature, which lets you find out more about a character in a book, a place, or a topic with one tap

The option to easily switch back and forth between reading and listening to a book without losing your place

The ability to customize the typeface, background color, and font size of a book

A built-in dictionary that can define a word with one tap

Amazon Prime members can read more than 1,000 titles for free

The new app has one catch, though: You can't purchase books or magazines directly through the Kindle app on iOS devices. You'll have to buy it through the Amazon website and send it to your phone or iPad.
